我想以百分比显示图像的RGB值。
例如,如果十六进制颜色为#000000
,如何将其显示为%代码(百分比),如rgb(0%,0%,0%)?
答案 0 :(得分:0)
试试这个,
function hex2rgb($hex) {
$hex = str_replace("#", "", $hex);
if(strlen($hex) == 3) {
$r = hexdec(substr($hex,0,1).substr($hex,0,1));
$g = hexdec(substr($hex,1,1).substr($hex,1,1));
$b = hexdec(substr($hex,2,1).substr($hex,2,1));
} else {
$r = hexdec(substr($hex,0,2));
$g = hexdec(substr($hex,2,2));
$b = hexdec(substr($hex,4,2));
}
$rgb = array($r, $g, $b);
//return implode(",", $rgb); // returns the rgb values separated by commas
return $rgb; // returns an array with the rgb values
}
<强>输出:强>
Array ( [0] => 204 [1] => 204 [2] => 0 )
//rgb(204,204,0)
